Vacuum Pump Coalescing Exhaust Filters

Vacuum Pump Coalescing Exhaust Filters

A coalescing filter is a device that is utilized for separating emulsions into their various components through several processes and works reversely to the emulsifier. These units are designed for use in vacuum pump inlet and exhaust systems. A coalescing filter separator can have up to 99.9999 percent efficiency and work in pressures exceeding more than 5,000 Pounds per Inch or PSI. Coalescing filters are found in the vacuum processing of foods, metals, heat treating, semiconductor mfg, gas plants, petrochemical and chemical plants, turbine, compressed air and gas mfg. systems.

Understand a Coalescing Filter

The process of coalescing is the separation of liquid droplets and aerosols from a gas. With a coalescing filter that is installed inside a housing, the wet gas is passed through the element from the inside to the outside. The interior capture layer is composed of highly efficient coalescing material while the exterior part is composed of a coarser drainage layer.

• It provides maximum safety to downstream equipment or atmospheric air.• It removes the maximum amount of solids and liquids from gas or air processing streams.• It removes more than 99 percent of aerosol mists and solid particles that are 0.3 microns or more.• It reduces the operating and maintenance expenses that are linked with contaminated gas.• This filtration system has a long service life while at the same time requiring less downtime and maintenance.

Operating Principle Of The Coalescing Exhaust Filter

The process of coalescing is the separation of liquid droplets and aerosols from a gas. With a coalescing filter that is installed inside a housing, the wet gas is passed through the element from the inside to the outside. The interior capture layer is composed of highly efficient coalescing material while the exterior part is composed of a coarser drainage layer.

Coalescing filters could be categorized into two kinds, which are the electrostatic and the mechanical coalescers. The electrostatic coalescing filter uses AC or AC fields or a combination of both while the mechanical coalescer uses baffles or filters to force droplets to coalesce.
